Abstract
Chemokine responses critical for inflammation and promotion of effective innate control of murine CMV (MCMV) in liver have been shown to be dependent on immunoregulatory functions elicited by IFN-alpha beta. However, it remains to be determined whether upstream factors that promote viral sensing resulting in the rapid secretion of IFN-alpha beta in liver differ from those described in other tissues. Because plasmacytoid dendritic cells (pDCs) are known producers of high levels of systemic IFN-alpha beta in response to MCMV,this study examines the in vivo contribution of pDCs to IFN -alpha beta production in the liver, and whether production of the cytokine and ensuing inflammatory events are dependent on TLR9, MyD88, or both.
